Thank you for your bug report. If you edit the signature path directory, could you check if `journalctl -f` lists apparmor denial errors when trying to write an email?
I would guess that the path is blocked by the snap sandboxing. If you use the fileselector then it goes through xdg portal which gives the other location but mention, but indeed that's a local path generated by the portal and not going to work on another machine (and probably not on the same after restarting either...) ** Summary changed: - Signature link changed + signature stored on a nfs share not working with the snap ** Changed in: thunderbird (Ubuntu) Importance: Undecided => Low ** Changed in: thunderbird (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2079039 Title: signature stored on a nfs share not working with the snap To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/2079039/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
